invoking a method of the grandparent from within the grandchild component

Question

invoking a method of the grandparent from within the grandchild component

My components are nested three levels deep:

<GrandParent />
   <Parent />
       <Child />

In the Child component, I have a button that, when double clicked, should call a function in the GrandParent component.

 <button @dblclick="this.$parent.callGrandParentFunction(model)"> Call Grandparent </button>

Using this.$parent, I can only access methods from the Parent component. Is there a way to go up one level higher and call a method from the GrandParent component?

There is a similar question on SO but it's related to vue2.

Utilize the provide/inject design pattern for better code organization:

Ancestor :

export default {
  methods: {
      someFunction(){
       //
      }
  },
  provide() {
    // using function syntax to access `this`
    return {
      someFunction: this.someFunction
    }
  }
}

In Descendant component :

export default {
  inject: ['someFunction'],
  created() {
    //execute the method 
    this.someFunction()
  }
}
